Description/Abstract

A study of the growth of fatigue damage in 2 x 2 twill woven composite materials,
subjected to cyclic tensile loading are described. Thermoelastic stress analysis (TSA) is
used to monitor the stress field. As a result of the damage, a net reduction in the
thermoelastic signal is observed. Laminates are found to be more resistant to fatigue.
